This might well happen if you are loading amssymb
after xunicode or fontspec (which requires xunicode ).
I don't see how this is related to use of todo though,
which makes no direct attempt to load any other packages.
Without you showing us your coding, it is only possible
to speculate on what could be the cause of the problem
that you are facing.
For instance, if your coding included something like
\todo{Don't forget to put \usepackage{amssymb} in the preamble.}
to remind yourself to update your own preamble,
then this might cause the package to be loaded
at an inappropriate place.
But this should cause a warning message anyway, so there
would be feedback that something is wrong.
Better would be
\todo{Don't forget to put \string\usepackage\{amssymb\} in the
preamble.}
or
\todo{amssymb}{Don't forget to put \verb|\usepackage{amssymb}| in
the preamble.}
